Utah 400 Series 1 Digital Routing Switcher


Utah Scientific has been involved in the design and manufacture of routing switchers for audio and video signals for over thirty years. Starting with our original AVS-1 router and moving through several generations of routing switcher design to the current UTAH-400 series for all signal formats, we have participated in the evolution of the broadcast television industry from analog composite through components and various forms of digital video and audio to today’s complex mixed environment of analog and multiple digital signal formats.

The UTAH-400 Series 1 was developed to provide a single platform for all digital router applications from very small to extremely large matrix configurations and to handle all digital signal formats. Thanks to an innovative matrix architecture the UTAH-400 is readily scaleable from 8x8 to 1152x1152 and beyond using a single family of matrix building blocks. In addition to this flexibility of configuration, the UTAH-400 Series 1 offers tremendous reductions in the physical space and power consumption requirements typically needed.

The UTAH-400 Series 1 uses a 3-board architecture consisting of an input board, a crosspoint board, and an output board. All frames and internal signal distribution components are designed for HD signal compatibility, providing full insurance that an SD system can be upgraded to 3G HD operation by simply exchanging the signal I/O modules. The UTAH-400 family consists of audio and video frames for 32x32, 64x64, 144x144, and 288x288 matrix sizes.

MODULE DESCRIPTIONS

INPUT BOARD The input board carries 8 identical receiver / buffer circuits for bringing the input signals from the rear panel into the matrix and delivering them to the crosspoint board. Each input circuit has a signal presence detector that can send an alarm to the frame’s alarm processor when it detects a loss of signal on the input. The Standard Definition version of the Input Board provides automatic equalization for up to 300 meters of type 8281 or equivalent cable at the input. The optional High Definition version of the Input Board offers 100 meters of equalization and can accept digital video signals at any data rate up to 3Gbps.

CROSSPOINT BOARDThe crosspoint board receives its inputs from the input cards and applies these signals to the crosspoint array. This array is fitted with the appropriate number of integrated circuit crosspoints for the frame in which it is to be used. The crosspoint board’s control inputs come from the system controller by way of a pair of Utah MX-Bus connectors mounted on the frame’s rear panel. The outputs of the crosspoint array are passed onto the Output Boards by the Output Bus.

OUTPUT BOARD The Output Board carries 8 identical driver circuits that buffer the signals from the Output Bus and present them to the connectors at the rear panel of the frame. Each output circuit has a signal presence detector for alarm reporting and automated troubleshooting and a reclocking circuit to ensure maximum signal quality at the output of the matrix.

DIGITAL AUDIO MATRICES The UTAH-400 digital audio switchers offers a number of innovative functional improvements over existing audio routers, including synchronous / asynchronous operation. The UTAH-400 AES switcher also offers the option to control the configuration of AES/EBU digital audio signals within the router to allow channel swapping and mixing, as well as “soft transitions”, completely eliminating pops and clicks that can accompany the switching of digital audio signals. UTAH-400 AES routers are available with balanced or unbalanced I/O ports. Matching transformers are available as an option.

INTERNAL SIGNAL FORMAT CONVERSION

The UTAH-400’s digital I/O cards can be replaced as required with cards that feature on-board Analog-to-Digital or Digital-to-Analog format conversion, giving the UTAH-400 the unique ability to provide analog inputs and/or outputs in blocks of 8 ports per board.

Utah 400 Series 1 Features

Signal Presence Detection — The UTAH-400 has signal presence detectors on all inputs and outputs, allowing the matrix to perform a number of unique functions ranging from simple alarms to automatic restoration of service on critical signal paths.

Crosspoint Redundancy Options — The UTAH-400’s unique architecture allows us to place fully redundant crosspoint assemblies in each matrix frame for the ultimate degree of operational reliability.

Internal Monitor Matrix — Each UTAH-400 Chassis is equipped with an SD-only internal monitor matrix for monitoring any of the output busses carried in that chassis. In multi-chassis systems, the monitor bus outputs from each chassis can be combined to provide a single monitor bus that can select any output in the system for monitoring.

Redunandant Power Supplies — All Utah-400 systems are supplied with dual power supplies for each frame.These supplies operate in a fully redundant configuration with complete alarm and monitoring capabilites

Redundant Control Cards — To further insure operational reliability, all UTAH-400 systems can be supplied with dual control cards in each frame.

Low Power Consumption — The UTAH-400 switchers are designed for extremely low power consumption. This translates to direct savings on operational expense and increased long-term reliability.

Fiber Optic I/O Option The UTAH-400 routers are available with optional Fiber I/O in place of the normal coax. Please consult the Fiber I/O Product Information Sheet for details.

Advanced Control Facilities

The UTAH-400 offers a glimpse into the future of routing switcher design with its unique signal presence monitoring capability. By continuously monitoring the presence of digital bit streams at each input and each output, the system can support automatic rerouting, or “protection switching”, to restore a signal feed that is interrupted by an internal or external fault. For example: Simple logic instructions can be set up to cause the switcher to switch a given output to a secondary input if there is loss of signal on the primary input. Using the same logic facilities, the system can check for signal presence on the active input when it detects loss of signal on an output before sending an alarm to the operator.

Large Router Systems

The UTAH-400 family also contains a variety of routers designed for system sizes larger than 288x288. Please contact your local Utah Scientific representative for additional details regarding larger systems.

The UTAH-400/32 is the smallest frame in the series, bringing all of the features of the UTAH-400 High Density Digital Routing Switcher family to smaller matrix size applications. Housed in a compact, 2RU frame that includes dual power supplies and dual crosspoint/controller cards, the UTAH-400/32 offers matrix sizes from 8x8 to 32x32.

The UTAH-400/32 uses the same I/O boards that are used in the larger frames. A major advantage of this approach is that if the matrix needs to be expanded to a larger frame, the I/O modules can be re-used in the new matrix.

To save space, the UTAH-400/32 uses a combination control/crosspoint card instead of separate cards for the two functions. The frame can optionally be fitted with Redundant Crosspoint/Control Cards that provide full backup against an internal path failure in the matrix.

UTAH-400/32 frames can be controlled by the same control bus connections used by the larger frames. They also offer the flexibility of having internal controller boards for standalone applications.

Thanks to the UTAH-400’s unique 8-port I/O cards, smaller matrices can be easily expanded in very cost-effective increments. The full range of I/O options is available in the smaller frame, including analog I/O cards for the ultimate in system flexibility.

Dual power supplies are standard — just like the larger frames.

Thanks to the UTAH-400’s unique 8-port I/O cards, smaller matrices can be easily expanded in very cost-effective increments. The full range of I/O options is available in the smaller frame, including analog I/O cards for the ultimate in system flexibility.

UTAH-400/64 frames use the same I/O modules as the larger UTAH-400 frames. The UTAH-400/64 frame can be fitted with an optional Redundant Crosspoint Card that provides full backup against an internal path failure in the matrix.

UTAH-400/64 frames can be controlled by the same control bus connections used by the larger frames. They also offer the option of having single or redundant internal SC-400 controller boards for stand-alone applications.

The UTAH-400/64 and /32 frames are especially well suited for use with the MC-400 Master Control Output Card for multi-channel systems where it makes sense to have the master control system work with a selected subset of sources rather than all of the sources available on a larger router.
